Objective

Exporting a LinkedSet attribute with spreadsheet HTML just returns the list of IDs of the linked objects, which is not very helpful for further processing.

Proposed solution

• Export the friendly names for the linked objects when localised, IDs otherwise.
• Add option to display the attribute as CSV in templates.

Hey @Hipska, thank you for your PR. It seems nice, but why IDs are exported when the object isn't localised ? Shouldn't it be only when there is no friendly name ? Except this small details, it has been accepted in functional review :)

This was to keep backward compatibility. If somebody relied on having the IDs, then they should still be there when using no localisation.
